carbon dioxide which is recognized as the major contributor to global warming as a greenhouse gas is formed when fossil fueels are combusted, as in electrical power plants fueled by coal, oil, or natural has. one potential way to reduce the amount of co2 added to the atmosphere is to store it as a compressed gas in underground formations.
if it is stored underground as a gas at 36.0 degrees celsius and 90.0 atm, what volume does it occupy?
